McNair has made just three starts and six appearances for the Red Devils this season but Van Gaal is keen to keep hold of the 20-year-old.

United's options in the centre of defence are limited with Marcos Rojo not expected to return until March after shoulder surgery.

Arsenal: Arsene Wenger still has a few faces to come back from long-term injuries but having not purchased an outfield player in the summer he is likely to invest this time around with a defensively-minded midfielder high on his agenda

Chris Smalling and Phil Jones have been Van Gaal's preferred pairing in recent weeks while midfielder Daley Blind has also filled in at centre-back this season.

McNair enjoyed a breakthrough season at Old Trafford last season, making 18 appearances in all competitions.

And he will be hoping Van Gaal's decision will lead to more playing time.
